Calling ConditionalBeginDestroy on an ActorComponent (instead of DestroyComponent) can lead to a crash due to the object not being correctly unregistered.
BeginDestroy doesn't unregister tick functions, and there is currently no warning being emitted to safeguard against use of ConditionalBeginDestroy on ActorComponent derivatives.
Create a component using NewObject<USceneComponent>
Allow the component to tick and register it with the world explicitly.
Call ConditionalBeginDestroy
This sets up the conditions to create a crash. The crash occurs if the object is destroyed before the stats system looks up the object.
The actual crash is sporadic and is best replicated by simply leaving the PIE session running.
